1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a configuration that indicates a sounding reference signal (SRS) resource set to be used for analog channel state feedback (CSF) and an association between the SRS resource set and a set of downlink channel state information reference signals (CSI-RSs), the configuration comprising a spatial relation information parameter that includes a CSI-RS index value identifying the set of downlink CSI-RSs;
measuring the set of downlink CSI-RSs associated with the SRS resource set; and
transmitting one or more SRSs for analog CSF using the SRS resource set and based at least in part on measuring the set of downlink CSI-RSs.
